Spamtrap Feeds

Spamhaus operates a number of automated spamtraps which gather information on IP addresses and domains that are sending mail to email addresses that are dormant; illegitimate; have never been registered; or contain typos.

Organizations that repeatedly send unsolicited emails that are caught in our spamtraps risk having their domains and IP addresses added to our block lists. If this happens, then their emails will be rejected by ISPs and any other entity that is using our blocklists to protect their mail streams from spam and malware.

A single email hitting one of our traps will not result in an IP address or domain being listed. Listing indicates repeated and sustained attempts to send unsolicited emails.

Genuine marketing organizations, that are sending bulk emails, have a vested interest in keeping their opt-in mailing lists clean and updated, so that their sender reputations are not damaged by hitting spam traps.

Spamhaus Technology makes some of its spamtrap data available as a raw data feed to approved organizations, to assist them with their list hygiene.
